I'm new to matlab. I would like to rewrite the following anonymous function into a standard function but I got struggled with the syntax.
Original function:
objc = @(w) [-mu'*w' w*C*w'];
My adjustment:
function [returns,variance] = MultiObjective(mu,C)
returns = -1*mu'*w';
variance = w*C*w';
end

The anonymous function has only w as the parameter; mu, C are embedded into the function definition with the values they contain at the time the function is defined.
Your function, would also have to pass w

Hi Jesus,
[ CORRECTED to include a minus sign ]
function [returns,variance] = MultiObjective(mu,C,w)
returns = -mu'*w';
variance = w*C*w';
end
Since it is a normal (non-anonymous) function, all variables are passed in on input, in whatever order you choose. (Of course you could define hardwired constants inside the function as well). Also, no need to multiply by -1.

Note that returning two variables is not the same as returning a row vector of two values.
